Acritarch distribution in the Middle Ordovician of Öland, Sweden : Ecostratigraphical or biostratigraphical signal?

The Middle Ordovician of the palaeocontinent Baltica provides some of the best preserved and most diverse acritarch assemblages of the lower Palaeozoic. A great number of widely used acritarch genera and species have been described from this area since the 1960s and many of these taxa are considered as biostratigraphically useful for both regional and international correlation. Here, we document t

Investigating the therapeutic potential of FLASH radiotherapy – a treatment planning study

Purpose/Background: Ultra-high dose rate radiotherapy (RT) has shown potential for differential normal tissue (NT) sparing (a phenomenon termed the “FLASH effect”), particularly for larger fraction doses (>5 Gy). However, transitioning to hypofractionation may increase late-reacting NT toxicity, counteracting the FLASH effect. This study evaluates whether FLASH-RT can provide netsparing for organs

Exploring the evolution of magnesium oxidation mechanisms by density functional theory

Magnesium (Mg) is an abundant metal which has been used in aviation, medicine, hydrogen energy storage, etc. However, Mg can be rather reactive, and therefore an improved understanding of corrosion and oxidation mechanisms can enhance the efficiency of these processes to control and widen applications. The study presented here investigates the mechanisms of oxidation from the initial to full monol

Compulsions in trauma-exposed patients with obsessive-compulsive disorder : Differences in prevalence and impact on treatment response

The effectiveness of exposure and response prevention (ERP), a front-line treatment for obsessive-compulsive disorder (OCD), is contingent on reducing engagement in compulsions, though recent research has found that certain compulsions may be less amenable to ERP. Given the impact of trauma exposure on OCD compulsions, the present study sought to examine whether compulsion-specific differences in

Molecular treatments to reduce catabolic effects in human meniscus explant models

A lumped parameter model of the coronary circulation incorporating time-varying resistance, intramyocardial pressure and vascular compliance

Conventional lumped parameter models (LPMs) simulate coronary flow incorporating intramyocardial pressure and vascular compliance, but assuming constant resistance despite its dynamic changes during myocardial contraction. We developed a coronary LPM incorporating time-varying resistance, intramyocardial pressure and vascular compliance to simulate phasic flow, critically evaluating key contributi

Familial risks of five types of osteoarthritis in first-, second- and third-degree relatives - A nationwide Swedish family study

Objective: Osteoarthritis (OA) is a common degenerative disease with a genetic contribution. However, no large nationwide family study concerning the heredity of OA has been published. This first nationwide study aimed to determine the familial risks of the main types of OA in twins, full-siblings, half-siblings, and cousins in Sweden. Design: The Swedish Multigeneration register was linked to the

Domesticating technology : Sociotechnical imaginaries of carbon capture and storage in Denmark

Carbon capture and storage (CCS) has in recent years gained new attention in national and corporate strategies for achieving climate goals. This is for instance seen in Denmark, where CCS was positioned as the largest single mitigation tool in the 2020 Climate Programme. As an example of how international imaginaries of mitigation technologies translate into national settings, this paper explores

Surface effects in quasiatomic layer etching of silicon

The current investigation explores the surface effects of quasiatomic layer etching (Q-ALE) of silicon (Si), focusing on the interplay of process parameters, such as Ar+ ion energy, and their impact on etch rate, surface roughness, and material damage. Using a chlorine-based reactive ion etching tool at varying radio frequency bias voltages, the ion energy distribution and etching characteristics

Not for children's ears? : Parents' insights into early childhood overweight and obesity treatment

This study offers novel insights into parents' experiences of healthcare interactions during weight-related visits. Data were collected through the More and Less Europe study, a randomized controlled trial evaluating a parent support program for children (aged 2-6 years) with overweight or obesity in Sweden, Romania, and Spain to capture parents' experiences of healthcare interactions. Semi-struct

Just energy transition and gender. A systematic review for feminist research

Through a systematic review this study critically examines existing peer-reviewed evidence on the often-overlooked gender dimensions of the just energy transition. We found 52 peer-review journal papers focusing on three main themes: (1) how energy production can worsen pre-existing gender-based vulnerabilities, (2) how energy consumption can reproduce gender-based energy poverty and (3) how femin

Qualitative study of fatigue in adults with primary mitochondrial disease : Development of the PROMIS Fatigue Mitochondrial Disease Short Form

Background: Fatigue is a debilitating symptom in patients with primary mitochondrial disease nPMD). Developing new treatments that improve fatigue is a patient priority but is hampered by a lack of fit-for-purpose patient-reported outcome measures (PROMs). We aimed to understand the impact of fatigue on the lives of people with PMD and develop a brief PMD-specific PROM to evaluate fatigue in clini

The use of extended reality in microsurgical free flap planning – A systematic review

Background: Dissecting free tissue flaps can be challenging and time-consuming. Imaging technologies are typically used to assist with preoperative planning. However, conventional methods have limitations that could potentially be overcome by extended reality technologies. This systematic review aimed to evaluate the current use of extended reality (XR) in preoperative planning for microsurgical f
